I completely agree with Peekawho. I was doing the rythm-pull out method for 2 years and every month I would be terrified if I became pregnant (never did) so I decided to get a copper IUD called "Paragard" I think that's the best choice I made at the time.
Its copper so there's no hormones with it. It can stay in place for 10 years or as long as you want, no interruption in sex, you don't have to remember to take any pills and its about 99.4% effective. I can honestly say that I loved having the IUD in place, I felt soooo calm about not getting pregnant. I didn't even feel it.
The only side effects are heavier bleeding and cramping in periods but it wasn't anything that 2 Advils didn't get rid of.
Good luck!
And you think you have headaches now....wait til you are pregnant and have a baby. I still have a headache, and my youngest is 29.
There are other options. What is wrong with a diaphragm? Or an IUD?
Lots of ladies use the rhythm method with the best of intentions. Many of them are called "mothers".
Its difficult...not as simple as avoiding sex on X day to Y day. In order for it to be even vaguely effective, you will have to check your temps, cervical position every day, cervical mucus, etc etc.
Ovulation can occur irregularly sometimes, even in a woman who usually has a 28 day cycle. That's why simply tracking days doesn't always work.
In a couple who is financially ready to add a child, who is emotionally ready, school completed (I know you were in college), in a long term stable relationship....going by the rhythm method might not be so bad, as a baby wouldn't be something that alters their lives in an unexpected way.
But to a young woman who is trying for a career, and may not be financially set and finished with school....its not a good choice.
There is no reason you can't use condoms every time. Or use a diaphragm and foam every time. Or get an IUD. Its simply called being reproductively responsible. May be messy, may not feel as great....but I have news. A baby is messy and inconvenient, and hugely expensive and will change your life forever. Put up with the inconvenience of birth control until you are completely ready for the responsibility of a baby.

You can get pregnant at any time during your cycle - the rhythm method is not effective at preventing pregnancy
The fact you have always had a 28 day cycle does not mean will have an atypical cycle in the future.
If your cycle is always regular and predictable at about every 28 days, you should ovulate between days 12-16.
Day 1 is the day you start your period.
Sperm can live for 5-7 days, usually 5 days is the more accurate guess.
So if you want to avoid pregnancy, avoid unprotected sex between Day 7 and, to be the safest, Day 20. Between Days 7-20, use condoms and/or spermicidal foam.
